IMPROVEMENT IN .LEVER-GRAPNEL.

The Schedule referred to in these Letters Patent and making part of the sarnfzl To lwhom it lmay concern:

Be it known that I, EDWIN B. DEWEY, of Pontiac, in the county of Oakland, in thev State of Michigan,

'lettersof reference marked' thereon, and making a part of this specification.

The drawing very fullv shows the nature of the invent-ion, which consists of two eurve'd levers, A and B, their outer extremities being pointed at O, as will be seen.

These levers are pivoted together at D, lthe lever A being shorter than the lever B, and pivoted to it as shown.

To the shorter arm E, of the lever B, and near its extremity, is pivoted a bearing-lever, F, provided at its lower extremity with a suitable hook, G, and at its otherend Wltli ears H,Whieh rest upon each side of the lever A, and act as guides'to control the position of the lever F.

I isa ring or socket, into which to insert a pole, of

any desired length, with which to raise theapparatus s to the rafter of abarn, fer instance.

NVhen used as a grapnel, to which to attach a tackle, i

for hoisting weights, hitch the tackle to the hook G; then, with a pole inserted in the socket or ring I, raise the apparatus to any convenient beam or rafter, when the points of the curved levers will enter the timber ofthe beam or rafter. The Weight being .applied directlyV to the lower end of the bearing-lever F, the

vheavier' such weight is,-the harder it will make the grapnel hold to the timber.`

That I claim as my invention, is- The bearing-lever-II, provided with suitable hook G, vwhen connected with curved and pointed leversA and B, and constructed and operating substantially as and for the purposes herein set forth and despiibed.
